Description

Keithley 237 High Voltage Source-Measure Unit Keithley 237 Features: Four instruments in one (voltage source, voltage measure, current source, current measure) 10fA, 10µV measurement sensitivity 1100V source and measure Standard and custom sweep capability including pulse 1000 source/measurements per second Four quadrant source operation Internal 1000-reading memory The Model 237 Source-Measure Unit (SMU) is a fully programmable instrument, capable of sourcing and measuring voltage or current simultaneously. This system is really four instruments in one: voltage source, current source, voltage measure, and current measure. The Model 237 will source voltage from 100µV to 1100V, and current from 100fA to 100mA. It can also measure voltage from 10µV to 110V and current from 10fA to 100mA. In the higher voltage range, current source and measure is 10mA maximum. The Model 237 can be programmed to perform source-measurements as a function of a stepped voltage or current. Voltage and current can be swept linearly, logarithmically, or pulsed. The START, STOP, STEP method of setting sweep parameters allows operators to become proficient at using the instrument very quickly. Sweep parameters may be appended (APPEND key) to obtain more complex test sequences. Creating custom sweeps of voltage or current is facilitated by the use of three waveform operations: CREATE, APPEND, and MODIFY. These allow the user to select waveform parameters, combine multiple waveforms, and select and change any points in a waveform previously crea - ted or appended. The Model 237 outputs and inputs are fully guarded, and the units are configured to allow four-terminal measurements. Two-terminal measurements are also available for more standard test procedures. These outputs can be floated up to ±200V from ground. The Model 237 Source-Measure Unit (SMU) is a fully programmable instrument, capable of sourcing and measuring voltage or current simultaneously. This system is really four instruments in one: voltage source, current source, voltage measure, and current measure. Applications This instrument addresses a wide variety of applications, including the characterization of semiconductor devices and the measurement of leakage currents or insulation resistance. It can be used standalone on a bench, in a test rack with PC control, or integrated with our Model 4200-SCS for high voltage semicconductor characterization. Wide Dynamic Range The Model 237 will source voltage from 100μV to 1100V, and current from 100fA to 100mA. It can also measure voltage from 10μV to 110V and current from 10fA to 100mA.
